Specific rates of solvolysis of 1-adamantyl fluoroformate in hydroxylic solvents have been measured by an electric conductivity method under various pressures. The activation parameters (△V≠o, △β≠, △H≠, △S≠) and average pressure within the solvation-shell of activated complex (charge development) have been estimated from the rates. Also, the selectivities for the formation of solvolysis products in aqueous ethanol have been determined by response-calibrated GC. The values of △V≠o, and △β≠ are both negative, but △H≠ is positive and △S≠, is large negative. This behavior is discussed in terms of electrostriction of solvation. From these results, it could be postulated that the solvolysis of 1-adamantyl fluoroformate have two major reaction pathway.
